    I have an 87 Blazer, I just bought it and noticed that it has an external oil cooler. I was wondering if that was standard or an add-on.

    Yeah it was a stock option. It was usually included in the "Towing Package"
    My 89 was orderd with the towing Package and it came with a oil cooler and a trans cooler.

    Mine has the oil cooler also. 88. Wonder if it hurts to get rid of it?

    Prolongs the life of the oil, (by keeping it cooler) so I'd assume it would be harmful to remove it. But thats probably an immeasurable difference, since the majority of vehicles produced don't have external oil coolers.

    I wouldn't pull it unless the hoses looked worn. Probably check with a mechanic to. To me it's just one more thing to break and have my oil presure goto zero!

    Not sure when they did it, but I would be somewhat concerned of the later ones popping, that look like power steering hoses. The earlier ones are steel braided, and there is no way they are going to pop. At most a hefty leak, even then I consider that damn unlikely. I do not like the power steering style ones, my friends '83's leak like a sieve, and miine are older.

    My 77 has the same external oil cooler and it has never given me any problems. I would leave it on. The GM engineers didn't spend all day designing it if it wasn't worth a dam. I beleive it helps to keep the engine temperature down too. If it aint broke don't fix it.
